Spacecraft Avionics Engineer

Overview

Avionics / Electrical Engineer – Build Flight-Critical Hardware for Next-Generation Space Systems!
El Segundo, CA | On-site

We are seeking an Avionics / Electrical Engineer to help design and deliver the electrical backbone of advanced spacecraft systems operating in demanding environments. This role is centered around high-performance hardware development, rapid iteration, and deep technical ownership. You will work closely with a small, highly capable engineering team to architect, build, and validate avionics systems that move quickly from concept to flight.

This position is ideal for engineers who enjoy working close to the hardware, solving complex multidisciplinary problems, and operating in environments where execution speed and engineering rigor matter equally. You will play a key role in bringing reliable, flight-ready systems online while helping shape system architecture and engineering best practices as the company scales.

We are a venture-backed aerospace startup focused on building advanced spacecraft systems that enable ambitious in-space missions. Our team combines deep technical experience with a startup mindset, emphasizing ownership, fast iteration, and first-principles engineering. Engineers here work across disciplines, move quickly from design to testing, and contribute directly to systems that are built to fly.
